...Last Day of Winter Weather Awareness Week...
On this last day of Winter Weather Awareness Week, we will discuss
wind chill, frostbite and hypothermia.
The wind chill is based on the rate of heat loss from exposed skin
caused by combined effects of wind and cold. As the wind increases,
heat is carried away from the body at an accelerated rate, driving
down the body temperature. Even animals are affected by the wind
chill. Wind chill charts are available from the National Weather
Service and can also be found online at weather.gov.
Frostbite is damage to the body tissue caused by that tissue being
frozen. Frostbite causes a loss of feeling and a white or pale
appearance in extremities such as fingers, toes, ear lobes or the
tip of the nose. If symptoms are detected, get medical help
immediately! If you must wait for help, slowly rewarm affected
areas. However, if the person is also showing signs of hypothermia,
warm the body core before the extremities.
Hypothermia occurs when there is a reduction of heat throughout the
entire body. Warning signs include uncontrollable shivering, memory
loss, disorientation, incoherence, slurred speech, drowsiness and
apparent exhaustion. To be sure a person is suffering from
hypothermia, take their temperature. If it is 95 degrees Fahrenheit
or less, immediately seek medical care. If medical help is not
available, begin warming the person slowly. Warm the body core
first, then the extremities. If necessary, use your own body as a
heat source.
